I recently came across the site empireavenue.com and found a whole new level of fun with social networking. This site allows you to play the social stock market. You link several of your social networks together and the site creates a stock value for yourself that increases the more connected and active you are across key sites like facebook, twitter, linkedin and also blogs. You can see who some of the most active people are and invest money (not real) in different social net-workers. This site is very interesting and fun to see how your stock is doing and to learn about others that are part of the social network scene.
When you do sign up invest a little in stock symbol SHEP.
Thanks and watch for more as we continue to understand this ever changing world of social media.
